Aircraft Fuel Tank Inerting

For years, nitrogen has been used to inert the headspace in combat aircraft fuel tanks. In 1996, the crash of TWA flight 800 brought the issue of explosive fuel vapors to the forefront for commercial aviation as well. Early on in the development of the OBIGGS (On-Board Inert Gas Generation System), On Site Gas engineers worked with a number of companies, and the FAA, to determine the best method for inerting the empty tanks of commercial aircraft. We continue to be a leader in the product design, development and consulting side of that business. As always, our engineers are available for consultation and custom system design.

Around the world, you'll find On Site Gas membrane and PSA tire and strut N2 pressurizing systems at work for the US military and commercial airlines. Our systems are custom engineered for individual volume requirements. They deliver FAA-approved nitrogen at any required pressure, and also store the gas for remote flight line or fixed-repair facility delivery. Whether you operate a small market top-off facility, or a high-volume major service center, we can size and build a system that not only fits your current needs, but can also be upgraded to operate as a source for fuel-tank inerting.

When air is compressed, the moisture and impurities within it become concentrated. A refrigerated air drier can lower the dew point from 70-80°F to as low as 40° F. But even at a 40° dew point, there is enough moisture to promote rust and corrosion in air-driven tools and machinery. What's the answer? Drier, cleaner gas from an N2 generator. Nitrogen produced with an input dryness of 40° F will have a dew point of as low as -40°F! This very dry, very pure N2 will double or even triple the life expectancy of air lines, tools, and machine parts.

A few years ago our founder, Frank Hursey, made a fascinating discovery: When nitrogen is sparged, or bubbled, into liquids, the oxygen level is reduced to a point at which most biologics and all botanicals cannot survive. We now have the patent on this process.

Photo labs, food-grade oil producers, packagers, pharmaceutical plants, chemical companies, HVAC cooling water towers, and many others now bubble 97-99% purity nitrogen into chemical baths at low pressure to prevent bacteria and algae growth. Even if the surface of the water is open to ambient air, sparging N2 kills algae. N2 is far less corrosive than ozone, and can be easily retrofitted to any recirculation or filtration system. We have worked on bulk carriers, oil tankers and ballast-water systems to develop N2 and hybrid systems that meet almost any sparging application. We can also design a system that will custom size N2 bubbles to boost cost-effectiveness.

On Site Gas systems Medical Grade PSA O2 generators are providing life-saving, medical grade breathing O2 for ambulance and emergency services. On Site PSA systems can provide a safe, efficient low-cost solution to the high cost of cryo oxygen delivery and cylinder filling. Many countries have followed the lead of the FDA and USP by setting required O2 purities at 93% with N2 as acceptable purity levels for any level patient. For those governing bodies who cannot be moved from 99%, On Site provides the only tested and proven reliable source of 99% PSA O2 in the world. Research has proven that PSA produced O2 has no negative impact on the patient even after long-term (years) use. On Site was the first company to gain acceptance for its PSA POGS military O2 system to provide O2, medical grade air and fill O2 cylinders in the field for the military.

The very first oxygen generation system we built was installed in a muffler shop. Today, there are over 1,000 On Site Gas units at work in every major muffler chain. The specially priced PRO 4 is designed to handle a shop with up to eight bays. Its ruggedness and durability in the oily environment is well documented. Now and forever, you can end the hassle of wrestling with O2 cylinders and placing undue stress on your back.

Autoclaves, ovens, and curing facilities for materials such as metal, carbon fiber, Kevlar and other high-strength or pre-preg fibers are an ideal application for non-cryo nitrogen. Maintaining a dry, oxygen-free atmosphere prevents metal from oxidizing, regardless of the temperature. Resins cure more quickly, evenly, and without bubbles in the dry, low O2 atmosphere of a nitrogen inerted oven. The quick drop in O2 is provided by a properly sized surge tank, while the consistent, continuous flow of N2 maintains the atmosphere throughout the cycle.

Like most living things, bacteria need oxygen to survive. If oxygen is removed from a product, bacteria cannot live and grow. No bacteria means no mold or mildew. No food spoilage. Organics or chemicals do not become infected. On Site Gas nitrogen systems are used to sparge and blanket liquid, powder and gaseous products every day. Since nitrogen is required 24/7 to prevent growth, an N2 generation system works best. Purity requirements to kill or prevent bacteria are relatively low (95%).

Invasive pest species transported in ballast water and discharged at ports continues to impact global ecosystems and threaten entire economies. On Site Gas Systems patented process for suppressing aerobic organisms (such as bacteria and algae) through sparging nitrogen into bilge liquids. We also have proprietary processes available that provide nitrogen hybrid packages for point-to-point, onboard, port-owned, tender-based and terminal-owned shore-based solutions. Our expertise is available to OEMs or direct customers. We can also provide proprietary solutions for bulk carriers.

For years, we’ve been providing N2 generation systems for beverage storage, CO2 mixing and beverage transport/dispensing to end users such as breweries, large venue contractors, vintners and manufacturers of beverage dispensing systems. The low nitrogen flow and constant demand required by beverage systems lends itself ideally to nitrogen generation.

Blanketing or purging is an ideal application for generated non-cryo nitrogen. Nitrogen purges furnaces of oxygen where the adhesive compound is applied to various tape materials, reducing the incidence of poor adhesive bonds, or hazardous atmospheres due to chemicals used for the bonding process.

The quick drop in O2 is provided by a surge tank sized properly to inert the oven while the consistent, continuous flow of an N2 generation system maintains the atmosphere continuously throughout the entire cycle. Purities can vary depending on the application; we can help you determine whatï¿½s best for your application.

Our work with bottlers has been one of our favorite studies. Together, we’ve explored and expanded the use of nitrogen and nitrogen generation systems in bottling various types of liquids and beverages. With the help of our customers, and participation with many bottling companies, On Site Gas has developed better systems to serve all the world’s bottling companies, from the smallest estate to the largest high-volume producer.

Because of the potential for oxidation, bright annealing requires high purity nitrogen when the oven temperature is over 1,500° F, however, the greatest volume of N2 is needed during the cooling phase. As the temperature drops, the percentage of O2 in the product stream can go up without any oxidation to the product. To this end, our proprietary purity selector switch/purity exchange valve is a perfect fit for annealing. The N2 system can be tuned down to deliver very high purity N2 as well. As the temperature goes down during the cooling process, the PFX valve can be adjusted to a different purity. Regardless of how it’s done, the annealing process is perfectly mated with PSA N2.

For years, phone and cable companies have been using our proprietary compressed air splice and switch dryer. Now, with the advent of 12- and 24-volt high-efficiency compressors, our no-moving-parts splice dryers can operate on virtually any power available. OEMs, cable service and optic-fiber companies can be free of bulky N2 cylinders forever. On Site Gas splice dryers operate independently for up to one year without service, and are as easy to install as placing a hanger in a closet.

Small autoclaves, ovens, and curing facilities for materials such as metal, Carbon fiber, Kevlar, and other high strength fibers (particularly prepreg) are an ideal application for generated non-cryo nitrogen. Maintaining a dry, oxygen free atmosphere prevents oxidation on metals, regardless of the temperature. Resins cure more quickly, evenly and without bubbles in the dry, low O2 atmosphere of a nitrogen inerted oven. The quick drop in O2 is provided by a surge tank sized properly to inert the oven while the consistent, continuous flow of an N2 generation system maintains the atmosphere continuously throughout the entire cycle.

Nitrogen is used to inert the headspace in chemical storage or process tanks. The purpose of nitrogen is to defeat hazardous or explosive environments, or because of the adverse effect oxygen has on certain chemicals. On Site has a nitrogen generating system that can work for either situation.

For over 100 years, coal mine fires have been an economic and ecological nightmare. Some active fires cost coal companies up to $2 million per day. On Site Gas provided the nitrogen gas that helped extinguish the Buchanan Mine fire in Virginia, and the Pikesville Mine fire in Kentucky. We also recently provided the nitrogen at the West Elk Mine fire in Colorado. These systems were at the site and operating within 24 hours of receiving the call to deploy. Insertion can be done through a borehole, or locally underground. Our N2 systems can deliver a constant large volume feed of high purity N2 with flows up to 1500 scfm and are extremely portable, with the ability to be placed at almost any location, no matter how remote.

New roasters, private packagers, and third-generation family businesses are all saving hundreds of thousands of dollars after switching to On Site Gas Systems (in many cases, our system is augmenting a liquid system). Whether your company is packing whole beans, ground coffee, or espresso pods, we have a solution for extending product shelf life and lowering costs. On Site Gas nitrogen generators are built on the basis of simplicity, reliability, low cost of operation, and expansion.

Whether you’re performing major maintenance or remedial treatments on an oil or natural gas well, replacing air with inert nitrogen on your coil tubing rig makes good sense; nitrogen is the gas of choice to displace oxygen, retard oxidation, break the “burning triangle,” and prevent explosions. On Site systems are hard at work now, 24/7, around the world in oil fields, on offshore platforms, in chemical facilities and manufacturing plants, heat treating facilities, grain silos — any environment where keeping a low oxygen atmosphere is a vital safety issue. On Site N2 systems can deliver a constant feed of high purity N2, with flows ranging from 2 scfm to 1500 scfm at low or high pressure. Turnkey N2 systems can be designed for placement on trailers or placed on skids. For immediate needs, our Field Services division can provide short, or long-term N2 system rentals. Reliability is the key differentiator that makes our PSA or membrane systems a logical choice.

From a medical standpoint, almost all scenarios involving the breakdown of infrastructure means that cryogenic oxygen can no longer be delivered. In other cases, transporting sufficient O2 to triage, stabilize, hold, and even perform surgery is a serious logistical issue. Portable, FDA-cleared, high-volume, noncryogenic oxygen generators capable of concentrating atmospheric O2 to a purity of USP 93%, can free emergency responders from dependence on cylinder, and liquid oxygen. On Site’s Portable Oxygen Generation System (POGS) is capable of providing FDA-cleared medical oxygen and FDA-cleared medical-grade air. The system is capable of filling any size high-pressure oxygen cylinder, and provides its own automatic backup in case of power failure or over demand. POGS provides air and oxygen at sufficient pressure to drive vents, anesthesia machines, and other devices requiring medical-grade air or oxygen. What’s more, POGS is the only O2 system of its size that has saved lives for every branch of the service on 6 of 7 continents.

If you’re in the aquaculture industry, you’re very familiar with the benefits of O2 — for fish growth, health, and maximizing population density. On Site Gas Systems has been providing 95% O2 systems to fish farms around the world for over 20 years. Reliability, simplicity, and ease of maintenance, particularly in the remote locations where most aquaculture is located. A few of our system's benefits are relativity & simplicity.

Nitrogen is an efficient, cost-effective way to displace oxygen and moisture. Today, more and more companies in the food industry realize that the purity and flow demands are ideally suited to on site N2 generation.

Like most living things, bacteria need oxygen to survive. If oxygen is removed from a product, bacteria cannot live and grow. No bacteria means no mold or mildew. No food spoilage. Chemicals do not become infected. By removing O2, all aerobic organisms are killed. (The only organisms not killed are anaerobic organisms, such as some viruses.) By controlling the amount of oxygen in the storage container, ripening can be controlled to a point where fruits and vegetables will mature and ripen at a perfectly controlled pace. On Site Gas Systems has been providing N2 to control atmosphere for growers and packers for over 10 years. With our proprietary purity/flow control valve, you’ll have fingertip control over the amount of O2 present in the N2 stream.

Anywhere there is fear of explosion — or one gas has to be kept separate from another — an N2 curtain is used. In enclosed areas or even open chemical plants, N2 is blown between gases to keep them apart. On Site Gas has been providing gas barrier systems to the chemical and oil industries for years without a failure. Our highly reliable PSA and membrane systems provide gas barrier protection in classified areas, safe areas, and even splash zones on ships, platforms, and in plants all over the world. Our experience in weather and explosion proofing is designed to provide a system in any climate, any location and any extreme.

Nitrogen is the ideal inert gas for blanketing or purging. It can be used to blanket storage tanks where various hydrocarbons or chemicals are housed, or used to reduce the oxygen content to a safe level. On Site can help you determine the purity level required for your application.

From large hand-blown Christmas ornament factories in Eastern Europe and Italy; medical and lab glass factories in Asia; light bulb manufacturers in Central America, to one-person shops in the US, glass blowers have been using On Site’s systems for years. Individual artists who work in remote areas or in the suburbs, often cannot get oxygen companies to deliver cylinders. What’s more, the high cost of O2 has put many small artists out of business. On Site’s O2 system is surprisingly affordable, and eliminates the need to move O2 cylinders forever. Our 95% O2 PSA unit is simple, reliable and easy to operate.

Today, On Site Gas N2 systems can be found inerting glove boxes and CA (controlled atmosphere) storage facilities all over the world. Since they require a relatively low flow of nitrogen at a continuous flow and pressure, CA boxes are ideal for N2 generation systems. Inerting and DeOxy applications such as the loading of white-phosphorous mortar shells, nuclear fuel-rod construction, PC board storage, pharmaceutical production, and disease research are just a few of the CA boxes for which we provide clean, economical PSA and Membrane N2.

On Site systems are operating now in some of the world’s most remote mines. Regardless of the altitude, climate, or conditions, our systems are increasing gold yield at a rate that pays for the system in a matter of months. By using oxygen to convert mineral sulfides to sulfates and processing them, gold yield can be more than doubled over standard ore gravity separation and concentration. By sparging 94-95% oxygen into a thickened flotation concentrate (which has been heated under pressure) an oxidized slurry results. Not only are U.S. sulphides converted to U.S. sulphates by the O2, but arsenic is converted to ferric arsenate. After neutralizing the oxidized slurry with lime, the slurry can be leached, and gold-bearing solutions recovered and filtered to create the additional yield. The volume of O2 required for the process dictates that the facility have easy access to either cryogenically produced, bulk liquid oxygen, or have the ability to produce its own oxygen. Even if cryogenic O2 is available from a reasonable distance, access for a bulk liquid carrier to the facility is usually a major issue. PSA produced O2 lends itself perfectly to such an application.

Nitrogen is used to inert grain silos and grain elevators, eliminating explosions in dust-filled atmospheres. Grain dust in these environments is very hazardous, and in an oxygen-rich environment, a spark could cause the dust to ignite.

In many processes, raw materials and various ingredients would be compromised if exposed to oxygen. The answer? Nitrogen inerting. Nitrogen is also used to inert the packaging of finished products, as well as other portions of the process.

Kilns and furnaces used for heat treating may be under pressure; that classifies them as autoclaves that require a greater volume of N2. Kilns and furnaces may also be used as a melting device. All of these processes have one enemy – oxygen. O2 discolors the product, and can dangerously weaken it. Any metal over 600° F will oxidize in the presence of O2. The purity for most metal applications is at most 99.99%; pressure 30-100 PSIG. Most are purge and fill applications that can be accommodated with larger or multiple N2 surge tanks instead of pressure-boosting compressors.

On Site systems are hard at work now, 24/7, around the world in oilfields, on offshore platforms, in chemical facilities and manufacturing plants, heat treating facilities, grain silos — any environment where keeping a low oxygen atmosphere is a vital safety issue. We also deal with special situations such as portable drum inerting, and decentralized off-site inerting. System reliability is the key differentiator that makes our PSA or membrane systems a logical choice.

Most injection molders require 99% nitrogen for their applications. Membrane systems are effective to approximently 99% while the PSA systems generates N2 up to 99.9995% and is more effective in many applications. We also offer multiple purity systems with PFX (Purity Flow Exchange).

The furnaces used to melt gold for jewelry or connectors have a silent enemy – oxygen. O2 discolors the product and can dangerously weaken it. Any metal over 600° F will oxidize in the presence of O2. The purity required for most metal applications is at most 99.99%; pressure 30-100 PSIG. Most are purge and fill applications, but all can be accommodated with larger or multiple nitrogen surge tanks instead of pressure-boosting compressors.

The low dew point of nitrogen (as low as -69° F) makes it an ideal choice for grain drying and kiln drying. Because of the need for a continuous feed of dry N2 into the bin or kiln, the 24/7 capability of an N2 generator offers a perfect solution. As a value-added feature, the lower O2 content of the N2 stream helps prevent the growth of organics, and can reduce the threat of explosions.

On Site Gas manufactures N2 generators for every lab application. We have a full line of high-efficiency compact nitrogen generators for LCMS at 99-99.5% purity at flows from 3 to 500 LPM. We also produce a low-flow, high-purity system for gas chromatography work that produces N2 at a purity of up to 99.9995% (5 ppm O2).

A lean and efficient shop has become vital to the success of a laser cutter. Nothing can provide you with more cost savings than to generate your own N2. On Site Gas systems are in dozens of laser cutting shops, producing from 99 to 99.995% purity with output pressures of up to several hundred PSI. Some of the questions we ask before we size a system are: Who manufactured your laser(s) and what is the wattage/model? What type of materials are you cutting? What is the thickest metal you cut? At what pressure do you cut your thickest metal? What size nozzle do you use to cut that thickest metal? Armed with that information, we can save you hundreds of thousands of dollars over bulk N2.

Nitrogen is used around the laser tip for two purposes; 1) to maintain the proper weld temperature, and 2) to get oxygen and moisture out of the beam path. Purity levels are typically 99% to 99.9%, but can vary depending on the exact requirements. Typical feed pressure for this laser process typically does not exceed 70 PSIG.

High purity nitrogen is used in many solder applications. Its benefits include reduced dross on solder pots, and reduced surface tension, which allows solder to cleanly break away from the solder site. Purities typically range from 99.99% to 99.9995%, but consult your manual for exact requirements.

On Site Gas systems Medical Grade PSA O2 generators are providing life-saving O2 daily to hospitals on five continents. Whether your country's requirements are 99%, 95% or 90%, we have a system that will suit your needs. From small rural clinics to large metropolitan hospitals, On Site PSA systems can provide a safe, efficient low-cost solution to the high cost of cryo oxygen delivery.

Medical ozone therapy is one of the most effective and beneficial ways of restoring optimal levels of oxygen to the human body. Oxygen regulates all of our activities. It is our most vital element for our well-being. Many scientist and doctors now believe that many health conditions are caused by the lack of oxygen. Healthy cells need oxygen to survive, and unhealthy cells like bacteria and viruses survive in the absence of oxygen. Oxygen therapy plays a vital role in maintaining your well-being. Oxygen along with food is the primary nutrient that cells use to generate energy. Oxygen therapy can add higher levels of oxygen to the working environment, raise energy levels, raise the immune system and increase your general vitality.

Because nitrogen is so dry, it prevents air tools from oxidizing, and makes them last 3-4 times longer. 95% nitrogen is acceptable, but usually under pressures in the 100-150 PSIG range. Skidded plug-and-play packages can easily accommodate the tool-driving needs of any size facility. Cabinet systems are available for larger facilities that can provide house air to the system.

These FDA approved, CE certified, modular systems are rugged but lightweight and portable. There are hundreds of reliable, battle-proven On Site Gas units operating today in Iraq, Afghanistan and other locations. Our POGS produces 33 LPM of 93% O2 at 50 PSIG and 30 LPM of medical grade air, and fills high pressure cylinders to 2200 PSIG. The system is completely stand-alone, and only requires a 208 Volt, 3 Phase power, including cylinder-filling booster.

POGS can be located 30 feet from the compressor and 60 feet from the power source. The entire system is completely modular and can be oriented in parallel or series. Its' feed air compressor, O2 delivery systems, O2 Booster and control panel are all plug-and-play, and are interchangeable with other units. The system includes automatic backup to supply oxygen if power is lost. Diagnostics include CO monitor with alarm and O2 Purity monitor with alarm. The system will produce O2 with full electronic failure. An optional high-volume booster is available to provide cylinder-filling capacity at 60 LPM.

POGS 33 is FDA cleared in the US for military, disaster relief, and emergency preparedness and also for medical air to operate various ventilation and anesthesia devices. Available in 50Hz and single phase.

On October 20, 2008, MSHA issued the Final Rule for submitting a mine seal design for approval. The Final Rule focuses on the strength, construction, maintenance, and repair of mine seals and also includes requirements for sampling and controlling the atmospheres behind seals. Under the Final Rule if a mine operator monitors and maintains the atmosphere of the sealed area as inert, seals must be designed to withstand 50 psi overpressure. If a mine operator does not monitor and maintain the atmosphere of the sealed area as inert, seals must be designed to withstand 120 psi overpressure or greater. The Final Rule does not require mine operators to upgrade seals constructed prior to May2,2007; however the atmosphere behind these seals must be continuously monitored and kept inert. N2 generators from On Site Gas Systems provide a safe and economical solution to the mining industry to keep the atmosphere behind sealed areas inert; either from a nearby underground location or from above ground. We have the expertise and experience to help you find the best solution.

Like most living things, bacteria needs oxygen to survive. If we displace the oxygen from a product, we remove a vital element that the bacterium needs to live. No bacteria means no mold or mildew. Food does not spoil. Chemicals do not become infected. By removing oxygen, we will kill any aerobic organism.

Most pharmaceutical companies have multiple nitrogen uses and purity demands. Lab GCs and some other low-flow processes require very low flow at very high purity (99.999%-99.9995%), while the LCMS requires only about 99%-99.9%. Labs may also need small volumes of liquid N2 for freezing. The balance of most pharmaceutical applications are blanketing, inerting and sparging (99%-99.9%). The latter is by far the largest demand, accounting for most of the nitrogen use in the facility.

Many companies believe that since they have high purity needs in the lab, they also have to have high purity or liquid N2 throughout the facility. Not necessarily so. Our small-lab N2 generation systems can provide the needed high-purity nitrogen for the GC and other high-purity users. A large PSA or membrane system can then be used to provide lower purity needs to the rest of the facility. We can come in and do a complete assessment for you.

The low dew point of nitrogen (as low as -40ï¿½ F/C) makes it an ideal choice for pipeline drying. As a value-added feature, nitrogen is totally inert; it displaces oxygen, retards oxidation, and prevents explosions. Because of the need for a continuous feed of dry nitrogen into the pipeline, the 24/7 capability of an N2 generator offers a perfect solution. An On Site system can deliver a constant high pressure feed of high purity nitrogen with flows ranging from 2 SCFM to 1500 SCFM. Turnkey N2 systems can be designed for placement on trailers or placed on skids. For immediate needs, we can provide short or long term nitrogen system rentals.

Mobile field hospitals can use the system as a direct feed to a medical application, use the medical air to operate equipment and also have the ability to fill cylinders. Emergency Preparedness Teams can now quickly deploy and start producing Oxygen for continuous use in any disaster without delays due to a compromised infrastructure or the need for other heavy equipment to unload the Oxygen system or deliver Liquid Oxygen.

On Site systems are providing high-speed printers with nitrogen for drying, and to prevent oxygen contamination for film production and separation. Purity needs vary depending on the process. We can provide a cost savings solution for you through our purity-flow exchange valve. With the PFX valve, your personnel can adjust the nitrogen purity with the simple turn of a handle.

Nitrogen is used to inert storage or process tanks as well as move product through pipelines at refineries. The purpose of nitrogen is to prevent hazardous or explosive environments, or because of the adverse effect oxygen has on certain chemicals. On Site has a nitrogen generating system - a PSA application such as the one pictured here, or membrane applications - that can work for either situation.

When used for lead-free soldering applications, high-purity nitrogen offers benefits such as reduced dross on solder pots, and reduced surface tension, which allows solder to cleanly break away from the solder site. Purities typically range from 99.99% to 99.9995%, but consult your manual for exact requirements.

For years, component level manufacturers and semi-conductor producers have been using nitrogen inertion. Whether in the fabrication of stacked dies, rework, or component solder bumping, N2 allows for a larger process window in the safety of minimal oxygen. With the advent of mandated lead-free soldering, the critical issues of flux chemistry aggressiveness have again been raised. When this aspect of process control is coupled with the smaller Delta T temperature window, N2 inerting boosts production success.

Controlled nitrogen atmospheres in reflow, wave, selective, and rework applications give engineers a larger process arena to work in. Nitrogen also helps during the liquidous state while the solder is completing surface wetting for a good bond. We began testing PSA N2 generation with reflow and found that purity levels required for reflow, wave and selective soldering range from 99.5% to 99.99%.

Injecting oxygen into your treatment basin dramatically increases bacteriological survival and regeneration. Your aerobics are well protected by using supplemental O2 to keep your PPM level up — regardless of the conditions, even in hot climates or summer months when O2 levels are at their lowest, and consumption highest. The consistent, level demand of injected oxygen makes PSA-generated O2 ideal to keep your plant operating and capital costs down. A simple, reliable On Site system will provide years of O2 production, without the ongoing expense and hassle of delivered cryogenically produced oxygen.

Before membrane technology, shipboard use of nitrogen for inerting propulsion, and bulk cargo combustibles, was dominated by combustion-based inert gas generators. On Site's expertise in offshore N2 production and explosive and/or corrosive environments can ease the burden of design and build for shipbuilders, engineering firms and ship owners. Our experience with the military has given us the capabilities needed to design and build systems that will withstand the harshest offshore conditions. We can design and build to your specs, or help you develop the specs for a custom design.

Nitrogen is used to inert the sintering process. (Sintering is the process of melting and compressing metal into molds). Oxygen (which causes rust) is removed from the environment by introducing nitrogen into the process. Inerting with nitrogen during the sintering process eliminates the effects of oxidation, thereby improving quality while reducing cost.

High purity nitrogen is required in many solder applications and provides several benefits. It reduces the dross on the solder pots. It also reduces the surface tension, allowing the solder to break away from the solder site more cleanly. Typical purity can range from 99.99% to 99.9995%, but consult your manual for exact requirements.

We can save you hundreds of thousands of dollars over bulk N2. A lean, efficient process has become vital to the success of laser cutting operations. Nothing can provide you with more cost savings than generating your own N2. On Site Gas systems are in dozens of laser cutting shops, producing from 99 to 99.995% purity, with output pressures up to 500PSIG.

We use nitrogen to drive medical air tools because the gas is so dry it prevents tools from oxidizing — and makes them last 3-4 times longer. The most technical version of N2 pressure driving occurs in the operating room. On Site Gas has developed an entire line of specialty generators that produce surgical, tool-driving medical grade USP 99% nitrogen at up to 180 PSIG using only oil-free compressors. Our N2 systems have been operating in hospitals for several years — saving money and eliminating the danger of changing high-pressure N2 cylinders.
